hinged members 1 forming the base bar are then folded on one another and at the same time the collapsed end frames are turned parallel to members 1 so that the canvas 15 connected at its ends to the top rails of the end frames will form a fiat loop projecting laterally from the folded frame. The canvas may then be wrapped around the folded frame as shown in Fig. 4. 4

I have thus provided a cot which may be folded into a compact form, and which when extended for use provides. a rigid construction without the use of side rails. The end frames are held rigid by the braces 8, and said end frames may be swung so as to longitudinally stretch the canvas 15 to any desired degree by tightening the straps 18. The members 1 of the base bar being held against folding by the abutment of their ends 3, the cot is thus longitudinally braced and held rigid by the straps; and at the same time the structure is braced against transverse strain by the rigidity of the end frames and the abutment thereof against the ground at points spaced transversely beyond opposite sides of the base bar.

I claim:

1. In a folding cot, a base bar comprising sections adapted to fold upon one another or extend beyond one another in longitudinal alinement, end frames comprising top and bottom rails and uprights connecting the same, means for forming rigid structures of said end frames with the top rails spaced above the bottom rails or collapsing said end frames with the top rails injuxtaposition with the bottom rails, means for mounting the bottom rails of the end frames on the respective sections of the base bar'so that the end framesextend transversely of the base bar with the top rails of the end frames adapted for vertical swinging movement away from one another base bar, a flexible body support connected at its respective ends to the top rails of the end frames, and adjustable connections between said top rails and the respective sections of the base bar beyond said end frames for swinging said top rails so as to tension the body support.

2. In a folding cot, a base bar comprising sections adapted to fold upon one another or extend beyond one another in longitudinal alinement, end frames comprising top and bottom rails and uprights connecting the same, means for forming rigid structures of said end frames with the'top rails spaced above the bottom rails or collapsing said end frames with the top rails in juxtaposition with the bottom rails, means for mounting the bottom rails of the end frames on the respective sections of the base bar so that the end frames when collapsed will extend along the sections of the base bar and when rigid structures are formed of the end longitudinally of the ment therefrom, a flexible of the base bar, a flexible body support connected at its respective ends to the top rails of the end frames, and connections between said top rails and the respective sections of the base bar beyond said end frames for swinging said top rails so as to tension the body support. 7 i

3. In a folding cot, a base bar, end frames comprising top and bottom rails and uprights connecting same, means for forming rigid structures of said end frames with the top rails spaced above the bottom rails or collapsing said end frames with the top rails in juxtaposition with the bottom rails, means for mounting the bottom rails on the base bar so that the end frames when collapsed will extend along the base bar and when rigid structures are formed of the end frames they will extend transversel of the base bar with the top rails of the end frames adapted for vertical swinging movement away from one another longitudinally of the base bar,'a flexible body support connected at its respective ends to the top rails of the end frames, and means for swinging the end frames away from one another soas to tension the body support between the top rails.

4. In a folding cot, a folding base, end frames connected to the base so as to prevent detachment therefrom, a flexible body support, and means for tensioning the body support between the end frames, and means for collapsing the end frames on the folded base longitudinally thereof with the body support wr oped around the collapsed end frames and olded base.

5. In a folding cot, a base, end frames connected to the base so as to prevent detachbody support, means for tensioning the body support between the end frames, and means for folding the base and end frames into longitudinal juxtaposition with the body support wrapped around the same.

6. In a folding cot, a base bar, end frames comprising top and bottom rails, uprights connecting the same, means for forming rigid structures of said end frames with the top rails spaced above the bottom rails or collapsing said end frames with the top rails in juxtaposition with the bottom rails, means for mounting the bottom rails of the end frames on the base bar so that the end frames extend transversely of the base bar with the top rails of the end frames adapted for vertical swinging movement away from one another longitudinally of the base bar and a flexible body support connected at its respective ends to the top rails of the end frames and tensioned by said swinging of the top rails.

7. In a folding cot, a base bar, end frames adapted to form rigid structures extending transversely of the base bar or collapsed structures extending along the base bar, the end frames when forming rigid structures being adapted for swinging of the upper ends thereof away from one another longitudinally of the base bar, and a flexible body support connected at its respective ends to the swinging upper ends of the end frames for tensioning said body support'between the end frames.

8. In a folding cot, a base bar, end frames adapted to form rigid structures extending transversely of the base bar or collapsed structures extending along the basebar, the
